This also drops support for python 2 and python 3.6, as the code paths in mach-nix do not currently work with those versions.
An incomplete list of things that still need to be done:
All the data for at least sdists containing a build-system section in pyproject.toml needs to be updated.
I suspect that this can't be done in github-actions.
When doing some testing via pushing to github (in #4), I was often seeing locking errors in nix, which probably needs to be addressed before this lands.
Given that extracting requirements uses import-from-derivation as a step during building, and that metadata-env and build-env are likely going to be identical between a bunch of packages, I suspect those errors are likely related.
There should probably be some spot-checking done of the generated data. I did this for one package: when the extraction worked, the data looked reasonable, but there were cases where I would expect it to work and didn't.
There is some code to extract errors in updater/crawl_sdist_deps.py, that will need to be updated to deal with the new structure of extraction and its output.
Note: I currently have no plans to continue this work in the future.
This uses https://github.com/DavHau/mach-nix/pull/401 to extract metadata from sdists, instead of a patched setuputils.
